This is a rural retreat like no other. Known as the Sixteen Doors House and designed by the firm Incorporated Architecture & Design, this is a modern cabin made practically transparent by the placement of sixteen doors and windows. Luckily, it’s surrounded by six acres of forest in the foothills of the Berkshires so privacy is a non-issue. 6sqft profiled the design project back in 2014; now it’s being offered as a vacation rental through Airbnb. For $300 a night, you can have your own tranquil experience at the Sixteen Doors House.
